0–100, higher is better. How it is calculated

Arista Networks is a leading enterprise technology company specializing in software-driven cloud networking solutions tailored for large data center storage and computing environments. Their platforms support Ethernet speeds ranging from 10 to 100 gigabits per second, positioning them as a key player in the cloud networking market. The website reflects a mature digital presence with comprehensive product and solution offerings, targeting a broad audience including enterprises and government sectors. The business model focuses on providing advanced networking hardware and software solutions to large-scale customers. Technically, the website is built on Joomla CMS with a modern tech stack including Bootstrap, jQuery, and integrations with HubSpot and Google Analytics for marketing and analytics purposes. The site is mobile optimized and demonstrates good SEO practices. Cookie consent is managed via OneTrust, indicating attention to privacy compliance, although explicit privacy and terms of service pages were not detected in the provided content. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data is notable and reduces confidence in domain registration transparency, but the professional website and consistent branding mitigate concerns. Overall, Arista Networks' website presents a professional and trustworthy front for their enterprise networking business. Strategic recommendations include publishing clear privacy and security policies, enhancing security headers, and providing direct contact information for security and privacy inquiries to strengthen trust and compliance posture.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

No critical or high findings. These medium findings are worth fixing next.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

  5. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Arista Networks holds a strong market position as a provider of cloud networking and data center solutions, serving enterprise and government sectors. Their competitive advantage lies in their software-driven approach and high-performance Ethernet platforms. The business model is B2B, focusing on hardware and software sales, network automation, and observability solutions. The company leverages partnerships and a broad product portfolio to address diverse networking needs. Growth indicators include extensive product lines and integration with modern marketing and analytics tools. The website's structured data and content reflect a mature and well-established business with a clear focus on technology innovation and customer engagement.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and cookie consent implemented. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No direct contact channels for incident response or security policy disclosures were found, which is a gap in transparency and readiness. The absence of WHOIS data is a concern for domain registration trust but does not directly impact website security. There are no visible vulnerabilities or exposed sensitive data in the HTML content. Compliance indicators for GDPR are minimal, with cookie consent present but no detailed privacy policy detected.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages prominently linked on the website.
  2. Implement and configure security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Provide clear contact information for security incidents, including a security@ or abuse@ email address and incident response procedures.
  4. Enhance GDPR and privacy compliance disclosures, including data retention policies and user rights information.
  5. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trust.

Technical notes

Notes

The website uses Joomla CMS with Bootstrap 3.3.7 and JavaScript libraries including jQuery and MooTools. Marketing and analytics integrations include HubSpot and Google Analytics, with cookie consent managed by OneTrust. The site is mobile optimized and has good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with multiple external scripts that may impact load times. Accessibility features are basic but present. There is an opportunity to modernize the tech stack and improve performance by optimizing script loading and updating frameworks. No critical technical debt or risks were identified from the HTML content.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
